DO NOT and I repeat DO NOT purchase Timbertech decking. It is an inferior product which is NOT maintenance free nor does it resist mildew nor does it look beautiful year after year. And it add insult to injury, this stuff is not cheap. This company should be sued for false advertising. I won't be surprised to see a Class Action suit soon and I intend to be a part of it.

am considering installing the Timbertech Earthwood product. Consumer reports has good review with excellent rating on mildew. Wondering if the posts here re mildew are from the Floorizon product, and if the installation was done according to TT specs. My contractor says he has never gotten a call back on TT, but he has used the TT Twin Finish line, which i dont like. Is anyone out there experienced specifically with the Earthwood line? Please reply, i have to get going on the deck! thanks

We've had TT Earthwood teak and walnut on our deck for a year now, and not many issues. I have seen mold, but it's in an area that gets dirty from debris washing off the roof during rainy periods.

Installed in September, 2008, I first saw the mold in the spring. It wasn't serious...just a small amount of surface mold on a few boards located under the roofline. My husband couldn't even see it with the elaborate "grain" pattern the teak has. I used a hose and light scrub brush to remove it, which took a little elbow grease, and I didn't see it again until now. I will wash it again before winter, maybe use Corte Clean this time, and see how it goes in the spring.

I should add that I have an upper and lower deck of identical materials. The lower is protected by an Undercover System, so it doesn't get wet...just damp from misty rains. Not much mold on lower deck at all.

So, in my experience, I would still recommend TT. The Earthwood is beautiful, especially with hidden fasteners. They're definitely worth the extra $. It is not entirely maintenance free, it does have to be cleaned a couple times a year, but so does everything.

I hope my mold issues don't become a nightmare like some of these other stories tell. I will not go down the road of using sealers, stains, etc. I don't even want to use chemicals because they always seem to break down the deck in the long run. Good luck to you.

We had a TimberTech deck installed as part of our new house construction that was completed in December 2006. Started getting a few nickel-sized black spots this past late summer/fall, and now they are covering the deck.

From the other posts in this thread, it doesn't sound like it's going to be very easy to fix. I'll give it a shot, but if it's going to be a maintenance disaster, I might just rip it all out & go with something else.

For some reason, my builder used pressure-treated wood railings rather than composite. These were painted shortly after being installed and there's a lot of paint blistering going on, so it might just be easier to rip all of that out too & start over.

Net-net, just because someone calls themselves a "custom" builder doesn't make them so, both in regard to the quality of contractors they choose as well as their materials.

Don't buy Timbertech. I have AZEK on another house and know people with Trex decks...these are truly "low maintenance" products. Timbertech is by no means low-maintenance.

Here are two links to the product I used. I had black spots all over my deck two years in a row and could have cried! I have Timbertech and thought it would be easy maintenance. It was so much work to clean and I tried so many products. My mother in law gave me a bottle of this product that she purchased at Costco. She had used it on her cement patio and loved it. It worked like a miracle! I applied it as directed once in the spring and I did not have ONE spot of mildew or mold on my deck all through till spring. I hope you'll have luck with it too!

save money by making your own solution using 1/4 cup oxalic acid (can be purchased at Marine hardware stores) and same amount of tsp per gallon, rinse and follow that with 1part household bleach to 2 parts water, scrub and rinse. You may find one or both solutions work for you but remember never to mix the two

This is my second year using this product. Before using WetandForget, I pressure wash the deck with Krud Cutter at medium pressure so as not to scare the deck. Then the next day I spray on WaF and forget it.

I REALLY wish I had seen all of these posts before I had my two decks installed, app. 650 sq ft. It not only cost me more for this product but the cost of the products to try and keep it clean is very high, not to mention a waste of my time since nothing works 100% or keeps it clean very long. There is black mildew over the entire surface of the deck that is not covered and in full sun. I can't keep it clean, and I am diligent to do so. The covered deck isn't nearly as hard to keep clean. However anything will stain it. I even have darker stains from where rain water hits one area. I would give anything to have known that this product was not the low maintenance product it was described to be. I would love to have the old standby pressure treated deck!!
